LibreSSL 2.7.4, 2.6.5 Released

We have released LibreSSL 2.7.4 and 2.6.5, security updates for the
current stable release branches. They contain the following changes:
* Avoid a timing side-channel leak when generating DSA and ECDSA
signatures. This is caused by an attempt to do fast modular
arithmetic, which introduces branches that leak information
regarding secret values. Issue identified and reported by Keegan
Ryan of NCC Group, CVE-2018-0495.
* Reject excessively large primes in DH key generation. Problem
reported by Guido Vranken to OpenSSL
(https://github.com/openssl/openssl/pull/6457) and based on his
diff.
The LibreSSL project continues improvement of the codebase to reflect modern,
safe programming practices. We welcome feedback and improvements from the
broader community. Thanks to all of the contributors who helped make this
release possible.
